Jets'n'Guns 2 stores most of its data files in content.zip. Extracting this is easy, but most of the files in the zip are encrypted. This program decrypts these files for you, making modding as simple as editing some ini files.

• Download the program from here
• Find your Jets'n'Guns 2 game folder.
  • You can open it through steam by right clicking on jng2 and going:
    • Properties... -> Local Files -> Browse...
• Copy the program you downloaded to this folder.
• Run it.
  • Windows will probably complain that the program might be unsafe. All I can really say to this is that all the code is here and open. You can easily verify this is not a virus.
• Once the program completes there should be a content folder.
  • This folder contains all the decrypted data. jng2-decrypt tells Jets'n'Guns 2 to load the game data from this folder, so if you edit anything in it, it should change the games behavior.
• If you wonna play unedited Jets'n'Guns 2, you can edit the content.txt file to be this:

  // dir = content
  zip = content.zip
